Engineer's Note

This 8GB DDR3-1333 RDIMM is purpose-built for server platforms, ideally suited for virtualization, memory-intensive databases, and mission-critical workloads where data integrity is paramount. Its registered signal architecture with ECC and dual-rank x4 organization enhances signal stability and memory bandwidth, ensuring reliable operation under sustained heavy loads.

Technical Specs & Insights

1. Registered signal type buffers command and address inputs, ensuring stable operation across fully populated server slots in dense rack deployments.
2. ECC error correction silently detects and corrects single-bit faults, preserving financial and transactional data integrity under continuous operation.
3. Dual Rank x4 organization exposes more bank groups per channel, sustaining high throughput for virtualized environments with mixed workload demands.
4. 8 GB capacity per stick provides sufficient memory footprint to run multiple virtual machines and in-memory caches without immediate node expansion.
5. PC3-10600 bandwidth combined with DDR3-1333 clocking delivers consistent response times for legacy enterprise applications while maintaining manageable power envelopes.

Why These Specs Matter

When managing a virtualization cluster running dozens of mission-critical VMs, a single uncorrected memory error can silently corrupt data and bring entire workloads to a halt. This Micron RDIMM (MT36JSF1G72PZ-1G4D1AD) is engineered to eliminate that risk. Its ECC technology continuously detects and corrects single-bit flips caused by cosmic radiation or electrical noise, which directly translates to uninterrupted uptime for your hypervisor hosts and transactional databases. With registered signal buffering, the module stabilizes command and address lines even when all 24 DIMM slots are populated, letting you scale to 192 GB or beyond without timing failures—critical for dense virtualized environments. The dual-rank x4 organization further enhances performance by enabling rank interleaving, allowing the memory controller to initiate a new access while another rank completes its cycle. For in-memory databases like Redis or SAP HANA, this means consistently lower latency and higher throughput under concurrent query loads. Operating at 1.5 V with a 1333 MHz clock and CL9 latency, this 8 GB stick balances power efficiency with the dependable speed your enterprise infrastructure demands, keeping your data accurate, your services responsive, and your total cost of ownership firmly under control.

Endurance & Reliability

Capacity Planning Guide for 8GB DDR3-1333 ECC RDIMM
This module’s ECC, Registered, and 240-pin attributes mark it as server memory, purpose-built for multi-socket stability and data integrity. Below are capacity recommendations for three typical enterprise workloads.

General Virtualization
Virtualized hosts thrive on balanced memory bandwidth. Populate all channels symmetrically with identical 8GB RDIMMs; a starting point is 6–8 modules per CPU (48–64GB), keeping NUMA nodes evenly loaded. For higher VM density, scale to 12–16 modules per server while preserving uniform dual-rank configuration to avoid performance hiccups.

In-Memory Database
These workloads require the largest possible RAM footprint. Install 16–24 modules (128–192GB) in a dual-socket server, filling every slot while adhering to dual-rank loading limits to maintain full 1333MHz speed. Balanced interleaving across all channels guarantees sustained low-latency access under heavy read/write pressure.

High-Performance Computing (HPC)
HPC applications depend on peak channel bandwidth. Populate one dual-rank RDIMM per channel—for a four-channel socket, use 8 modules (64GB) per node. Avoid mixing capacities or ranks; identical population keeps all channels operating at maximum throughput and prevents bandwidth penalties during parallel workloads.
